I'm planning a trip to RRG in the spring. I haven't been there in over 10yrs so I'm curious as which guide book is the most up to date. I'll be doing mostly sport climb with some minor trad routes possibly. Thanks for the suggestions!
The guide book was split in the latest iteration into a North Region book and a South Region book. North is mostly Trad, South is mostly Sport, but there's gems for both in each. South is currently out of print because a new printed South Region book will be available in March, supposedly.
I'd buy the south book, and supplement with the online guide. Or just go to Muir, where everything is tagged.
